History
The early story of BBJ started around the mid-thirties. The ever-increasing traffic movement between the twin cities of Calcutta & Howrah demanded a wider and stronger bridge in replacement of the then existing pontoon bridge. The authorities accordingly decided on building a cantilever bridge across the river Hooghly. The job undoubtedly called for greater expertise. So the three engineering companies – Braithwaite, Burn & Jessop – came together and floated a new company. Thus on 26 January 1935 was born BBJ, The Braithwaite Burn & Jessop Construction Company Limited.

The onward march began in 1941 with the Howrah Bridge, later, named Rabindra Setu. Later in 1991 achievement is the second Hooghly Bridge or Vidyasagar Setu. In between BBJ constructed number of engineering structures spread across the country and abroad.

The first Ganga Bridge of independent India Rajendra Setu at Mokameh-Barauni in Bihar, Yamuna Bridge at Delhi, Godavari Bridge at Rajamundry, Krishna Bridge at Vijayawada, Brahmaputra Bridge at Pandu are some of the known achievements of the company.
